 around to it some time. If you have any good ideas, please let me know.
 
+* login/sulogin/passwd/getty/etc are part of tinylogin, and so are not
+    needed or wanted in busybox (or else I'd have to link to libcrypt).

+    ping.  nfs mounting and syslogd (network logging) will remain in BusyBox.

 -----------
 
-* Allow tar to create archives with sockets, devices, and other special files
-* Add in a mini insmod, rmmod, lsmod
-* Change init so halt, reboot (and poweroff) work with an initrd
-    when init is not PID 1
-* poweroff
-* du
-* mkfifo
-* hostname/dnsdomainname
-* ping/traceroute/nslookup/netstat
-* rdate
+* dnsdomainname
+* traceroute/netstat
 * hwclock
-* login/getty
-* free

-* expr (maybe)?

+Running the following:

+       sed -ne 's/.*undefined reference to `\(.*\)..*/\1/gp' | sort | uniq
+
+reveals the list of all external (i.e. libc) things that BusyBox depends on.
+It would be a very nice thing to reduce this list to an absolute minimum, and
+then create a microLibc to provide these functions.  There is no good reason
+for GNU libc to be so big.  I'm sure it can be a lot better.
+
+(BTW, this is more informative if BB_FEATURE_NFSMOUNT is turned off...)
+
+Most wanted list:
+
+    [andersen@slag busybox]$ grep -l getgroups *.[ch]
+    test.c
+
+Policy violation.  getgroups uses libc nss, which is unlikely
+to be present in an embedded system.
+
+-----------------------
+
+Compile with debugging on, run 'nm --size-sort ./busybox'
+and then start with the biggest things and make them smaller...
+
+-----------------------
+
+ du.c probably ought to have an -x switch like GNU du does...
